Rolling force calculation and parameter influence analysis of wide and thick stainless clad plate
Stainless clad plate is a metallurgical combination of base material (carbon steel or low alloy steel) and cladding material (stainless steel) through high-temperature heating and pressure deformation, making it an integral laminated material with special properties. Based on corrosion resistance considerations, wide and thick stainless steel composite panels have broad application prospects in high-end industries such as petrochemical, marine, and nuclear power. Compared with the explosive compounding method and explosive-rolling compounding method, the method of producing stainless clad plate by interlayer vacuum rolling is more suitable for large-scale production.
Scholars from Yanshan University conducted a stress analysis on the vacuum hot rolling deformation process of wide and thick stainless steel composite plates. The hot rolling deformation was divided into two intervals, I and II, and the principal stress method was used to establish the force balance equation for each interval. According to the boundary conditions Calculate the length of each deformation zone and the pressure of each deformation zone with the yield criterion, establish a mathematical model of rolling force calculation, and analyze the influence of rolling process parameters on different stress distributions in the rolling interval of wide and thick stainless clad plates.
Substituting the actual parameters into the rolling model calculation formula, using Matlab programming to obtain the theoretical calculation value, and compare it with the actual measured value. The research results show that the rolling force model can be used to predict the size of the rolling force and meet the engineering requirements. The research of the rolling compound process is helpful to optimize the forming process and predict the product performance, which provides a reference for the future research and development of such materials.
